chest, sides, and under tail-coverts are ochreous buff, the middle of the lower breast 
and abdomen alone being pale sulphur-yellow; crown and mantle dull brownish 
olive. The specimens from Humaytha and Marmellos also show a decided ochreous 
tinge on throat, chest, etc., though to a lesser degree.

This bird is practically identical with specimens from Trinidad and Venezuela, 
the under parts being bright yellow, the chest and sides strongly tinged with olive- 
green. An adult obtained by Mr. Hoffmanns at Humaytha, on his first journey 
to the Rio Madeira, and an immature male from Borba secured by Natterer, 
are paler yellow on the belly, and the chest is scarcely shaded with greenish.
